Monolith composite catalysts based on ceramometals for partial oxidation of hydrocarbons to synthesis gas

摘要

MicroChannel ceramometal monoliths of a high thermal and mechanical stability have been synthesized via hydrothermal treatment of powdered mixtures containing aluminum and additives (oxides or/and Ni-Cr(Co) alloy) followed by calcination. The phase composition and textural properties of monoliths depend on the additive nature affecting the aluminum reactivity toward oxidation and the interaction of remaining Al~0 as well. MicroChannel ceramometal monoliths and catalysts based on them ensure a high performance and stability in CPO of hydrocarbons at short contact times.
